Numerical Modelling of Alkali Aggregate Reaction

This reference book presents the theory and methodology to conduct a finite element assessment of concrete structures subjected to chemically induced volumetric expansion in general and alkali aggregate reaction in particular. Subjects treated are:
Constitutive model: Theoretical model, equations, constitutive driver.
Micro-Model: Example of a micro model which simulates the expansion of an aggregate, and transition to a macro-model.
Macro Model: How to prepare the relevant data prior to analysis, and how to conduct the numerical simulation. How to perform a Matlab based system identification to determine key AAR parameters.
Sensitivity Analysis: Through parametric studies assess the importance of key parameters (such as what should be the smalles time step, how important is it to model temperature spatial and temporal variations).
Validation: Assessment of the model through simulation of simple laboratory tests.
Case Studies: Two detailed case studies will be provided; a dam and a heavily reinforced massive concrete structure.
Field Assessment.

Victor E. Saouma is a professor of civil engineering at the University of Colorado Boulder . He joined the department in 1984 where he teaches courses in structural analysis. He is currently president of the International Association of Fracture Mechanics for Concrete and Concrete Structures (IA-FraMCoS) and was formerly the director of the University of Colorado Fast Hybrid Testing Laboratory which is part of the George E. Brown, Jr. Network for Earthquake Engineering Simulation.

Over the years his research interests have varied but are always driven by a desire to apply first principles toward the solution of engineering problems. This has included innovative experimental work such as centrifuge/shake table tests of dams and real time hybrid simulation of reinforced concrete frames, as well as development of constitutive models, development of nonlinear finite element codes, modeling of concrete.

His research has primarily been funded by EPRI (Electric Power Research Company), TEPCO (Tokyo Electric Power Company), and government agencies such as the National Science Foundation and the Oak Ridge National Laboratory. As a consultant, his work has involved the seismic safety of very high arch dams, delamination in nuclear power plants, and AAR induced damage in infrastructures. He has over eighty peer-reviewed journal articles.
